separated from the water and other substances which distil over :from the raw material.

Another object of the invention is to provide means in a turpentine still for indicating the height of the ,material within the still and for warning the distiller when the contents of the still are boiling too rapidly thereby preventing any of the solid matter from going over into the condensing,r apparatus.

Another object of the invention is to provide. an apparatus for use in connection with a turpentine still whereby when the turpentine is being distilled, the turpentinc may be collected in one vessel and the water separated therefrom and conducted to a sec# ond vessel, said means being operable to prevent any entrance of water into the first mentioned vessel when the charge of thc still is about exhausted at which time only water will be distilled.

A still further ob ect of the invention is to provide an automatically'operable means for placing), receivers beneath the outlet of the still whereby to receive the turpentine vtherein 'and subject the same to a final separating process, said means being operable to place one container after another beneath' the outlet as the contalners become filled.

, A still Jfurther object of the invention is to provide means for operating the turpentine receiving means mentioned in the preceding paragraph, said means being operable by the weightof the water collected in a vvessel from the condenser of the turpentine still.

1n addition to the foregoing my invention comprehends improvements in the detalls of construction and arrangement of the parts to be herrinafter more fully described and particularlyl set forth in the appended claims.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference tliroi'lghoutthe several views in which they appear i 4 F'gure l, is a diagrammatic view in side 'elevation of. a turpentine still illustrating the embodiment therein of my improved separating apparatus.

Fig. 4, is a detail view in section of two ofthe separating elements of my apparatus.

Fig. 5, is a view in section of the vessels containing the alarm and still gaging apparatus.

Fig. 6, is a view in section taken at right angles to the section of the preceding figure, and

Fig. 7, is a detail view in section taken on the line 7-7 of Fig. 1.

With reference to tl'ie drawings 10 indicates a turpentine still of conventional type mounted in a'furnace 11 and having an out-4 let 12 at its upper portion leading to a worm condenser' 123 of conventional type, the outlet o'l' the worm being indicated at 14.

An opening is formed in the upper portion of the still over which opening is clamped a device indicated generally at 15 which comprises an alarm mechanism and means for suspending a float within the still. This device comprises a bottom plate 1G yfrom which depends a pair of spaced rods 17 between which a oat 18 is suspended, said Hoat being movable vertically 'and guided by said rods. The device 15 comprises a hollow enlarged portion 1.9 having a gong 20 securedto the outer side thereof with a hammer 21 adapted to engage the lgong, pivoted interiorly of the enlarged. porf tion 19 at 22, and havingr avbifurcated porcated in a cylindrical casinp,r 28 disposed some distance away vfrom the still. The oppositeend of the fiexible element 24 is then lconnected to the upper end of a second iiexible element Q9 provided within the casing 28, said flexible element 29 passing over a pulley 30 within the casing and having at its opposite or lower end connected thereto a pointerl movable vertically upon aguide rod 32, the point of connection of theflexi- Able elements 24 and 29 having connected thereto a weight 33 whereby the pointer 31 is urged toward an upward position. rThe weight l33V however, 'being overbalanced by the weight of the float within the still. YA

Y scale 34 may be placed within the casing 28 in proximity to the p ointer-and an opening` may be provided in the casing whereby the proximlty of the pointer to any of the graduations on the scale may be observed..

From the foregoing description it will be obvious that the level of the fluid within the still may be known constantly by obserw ing thc height'of the pointerl within the casing 28, and furthermore as the contents of the still rise, as it frequently does, this fact may be known t0 the distiller who cian then lower the heat to preventboiling over v end of 'which Ithe outlet 14 of the worm 13 projects. These elements are set forth in detail in Fig. 4 from which it will be noted that pulley 39 is mounted in a bracket depending from the top portion of the tank 36, a flexible element 40 passing around said pulley and having at' one end a float 41 with the opposite end connected to the le# ver 42 of a valve 43.' The valve 43 is interposed in a pipe 44 having 4its open end within the casing 36 disposed at a predetermined point, acoil spring` 45 having-one end secured tothe handle 42 and the oppos l site end to the interior of the casing acting to normally retain said valve in a closed position. vThe iloat 4l is preferably of the type .comprising a hollow air tightbody having relatively thin walls and should have buoyancy sufficient to Permit it to float upon water but to sink in turpentine.

A pipe 46 is connected at one end to the. lower end of the casing 36 with the opposite end of the pipe leading into the upper portion of a horizontally disposed cylindrical casing. 47 located adjacent the casing 36, withv the endof the pipe 46 extending rWith-A in the casing to a pointY` adjacent the bottom thereof as indicated in Fig. 4 of the draw-v ings. The pipe 46 is formed with an u'pwardlyk extending, inverted U-shaped bent portion 46, extending to -a point above 'the I' pipe 44 and on a level with the valve 43.y

The lower end of saidfpipe-46 is preferably placed adjacent the outlet pipe 48 of the casing 47 for a purpose which will be pres-` The pipe .44 mentionedv to discharge into a cup 49 mounted on one end 'of' a lever 50, fulcrumed at 5l within the tank, and having its opposite end connected through the medium of a link 52 to a valve 53 which controls the opening of a depending turpentine discharge pipe 54.

The cup is provided with a greatly conl s'tricted opening 49 and the lever 50 should be balanced so Aas to permit the valve 53 to remain in closed position'when the cup 49 is empty, n

The outlet 54 of the'veSsel-47 discharges into a bucket which is pivotally mounted upon one end of a lever 56, ful- Vcrunied at 57 Vand having its other end pro vided-with a weight 58 to overbalance the weight of the bucket and to elevate the bucket' when the same is emptied. The bucket 55 is normally disposed about a tank 59 providedv with an outlet pipe 60 which is connected to an opening located adjacent the upper end of the tank. An outlet opening is also formed adjacent the lower end of the tank and a pipe 6 1 is connected thereto having a joint 62 securednthereto and the branch pipe 63 extending from said joint. A flexible element 64 "connects the .branch 63 of the pipe with the weighted end of thelever 56 wherebyv the branch63 is retained in an elevated position so as to dispose. the upper end of the branchabove the normal level of fluid within the tank 59 when the bucket 55 is depressed. its bottom with a restricted opening to permit the contents thereof to flow slowly therefrom.

A turntable 65 is mounted to rotatel in a horizontal plane beneath the outlet pipe 6() of the tank 59, said turn table being mounted upon the shaft 66 having a bevel gear 67 .secured lthereto for `mesh1ng engagement with the bevel gear 68 mounted upon a horifzontal shaft 69. The shaft 69v also supports1 a wheel 70 'having a plurality of radial arms 71, eaoh arm carrying a bucket 72 at its outer` end. A trough 73 is provided having its'discharge end located above the bucket 7 2 so as to discharge thereinto one bucket at a time, the other end of the trough being located So esto. receive the contents ofthe tank 59 whenthe'branchv 63 of the pipe v61 is lowered to discharge into said trough.

The turn-table 65 carries a plurality of' .tanks 74 in uniformly spaced relation veach f tank having 'an outlet pipe 75 connected to an opening in the lower kend of thetank, said The bucket 55 is provided in.

' charge into a is connected to the and is mounted in guides exterior of each of the tanks 74. The upper end of the rod is directed into the tank and is provided with a iioat 77 to float on waterand sink in turpentine. The lower end of the rod 76 is then bent at right angles as at 78 for engagement with the stop. A bracket 479' is mounted adjacent the peripheryA ofthe turn-table and is formed with a vertically extending slot A80 in which a block 8l slides. The block is adapted to be positioned so as to be engaged by the out-tuirned'end 7 8 of the rod 76 when the ioat 77 is in'a depressed position, but to clear said stopA when the float is elevated, or when the block 81, is in the lower end of the slot 80.

The outlet of the tank 47 is connected to a pipe v48 which terminates at a point to disbucket 82 which is mounted on one end of the lever 83 pivoted as at 84. The opposite end of the lever 83 carries a weight 85 whereby to overbalance the weight of the bucket 82 when the bucket is empty. The weighted end of the lever im block 81 whereby the block may be elevated when the bucket 82 is depressed. The bucket 32'is normally suspended over a tank 86 having an outlet pipe 87 connected to a point adjacent the lower end thereof and an outlet pipe 88 connected to an opening located'ad3acent the, upper end.

The construction of my apparatus having been set forth above in detail its operation may be brieily stated as follows The products of condensation from the worm 13 are led into the chamber 3 6. The chamber 36 also provides for a preliminary separation of the turpentine and water, the turpentine being of a lesser specific gravity, floats upon the surface of the water, as long as the level of the water is below the upper end of the pipe 44 the valve will be retained in open position sincethe float 41 will sink in the lturpentinel As the level of therwater in the chamber 36 rises, the float 41 is carried upward thereby permitting the tension of thespring v45 tov relax so as to move the valve 43 to closed position. This movement toward a closed4 position will however not take place until the float 4l has risen sufficiently or until the level of the water reaches the mouth of the pipe 44 within the chamber. Prior to this however, turpentine wii How into the pipe 44 and into the cup 4S ofthe container 47, rapidly filling the cup so as to cause the same to move downward and raise the valve 53. As a result the contents of the container 47 will flow out through the pipe 54, and as long as 'the cup 49 is depressed, water from the chamber 36 as well as turpentine flowing from the pipe 44 will flow from the vessel 47 out through the pipe 54, and as long as the cup 49 is depressed, water from the chamber 36 as well 'as turpentine flowing from the pipe 44 will flow from the vessel 4r out through the pipe 54 into the receptacle 55 which happens to be disposed beneath the discharge end of said pipe 54. It is to be noted at this time that if only Water is being condensed in the worm, it will pass .out through the pipe 46' about as fast as it enters the chamber 36, and will therefore l pass into the container 47 and effect anexit therefrom through the pipe 48. In this manner, no Huid is permitted to discharge through the pipe 54 unless accompanied by the slightest quantity of turpontine. As long as turpentine is condensed the bucket 55 will be held in a depressed position and the branch 63 of the pipe 61 will'be retained. in an elevated. position to retainthe contents of the tank 59 therein. As the tank 59 becomes filled and the level of the turpentine reaches the opening to which the outlet pipe 60 is connected. The Iturpentine ows through the pipe 60 and is caught in one of the tanks 74 mounted upon the turntable. As the tank 74 gradually tills, the float .77 is raised until the lower end of the rod 76 is elevated so as to clear the top of the block 81. Vhen the charge in the still4 is eX- hausted and turpentine no longer passes through. the apparatus; the contents of the bucket 55 will eventually escape through the constricted opening thereof whereby the vbucket -will be `elevated by the depression of the weighted end of the lever 56, the

downward movement of said weightedend through the shaft 69, gears 67 and 68 to the shaft 66 thereby rotating the turntable so as to remove the filled tank 74 -frpm beneath the discharge spout 60 and to substitute an empty tank, the movement of the turntable being limited by the engagement of the rods 76 of the empty tank with the stop block 8l, so as to position the empty tank iua position to be filled. .During the passage of fluid of any character through the condenser,

' either water or tnrpentine the bucket 82 will be constantly filled and as a consequence the block 82 will be retained in an elevated posi-- tion for engagement. by the depressed rod 76 of the vtank 74 of the turn table. When iso y tank 74 into a position to be filled. It will be notedl that in the next adjacent empty 'tank the lioat Z7 will be lower and hence the lower end of the rod .7 6 will engage the block 8l, even in the lowered position of said block with the result that the turntable is properly positioned to 'bring the tank 74 beneaththe pipe 60. The buckets 5 5 and 82 will empty at the same time so that the lowering-oi the pipe 63 and the consequent operation of the turn-table will take place 'simultaneously with the lowering of the bladel to permit the turn table to rotate. The turntable will be held against rotation because the doet 77 in the tank 74 will not lioat high enough to release the turntable. The entire 'apparatus with the exception of the still and condenser should. be inclosed ina housing and the same locked to prevent tampering of the stiller with the apparatus, the key being in charge of an authorized person. A valve controlled pipe 13 is led from the condenser to'supply cold water to the tank 8G to cool the turpentine, l

Thus it will be seen that l have provided an apparatus for distilling turpentine, whereby the act of separating lturpf'antine from the water takes place automatically,

. of with water.

and whereby the product of the still may be tested at times to determine the quality of the product and the extent of dilution there- While l have illustrated and described my invention with some degree of particularity, l realize that in practice various alterations 'thereover may be inade, and I therefore desire to reserve the right and privilege of changing the- .form 'of they details of construction, or otherwise altering the arrangement of the correlative "parts without departing from the spirit ol the invention or the scope of the appended claims.
